+"""Rename ``lfx-*`` bundle packages to their ``-nightly`` counterparts.
+
+Bundles under ``src/bundles/*`` follow the same package-rename convention as
+``langflow``, ``langflow-base``, ``lfx``, and ``langflow-sdk``: for nightly
+builds, the distribution is published as ``<name>-nightly`` so the regular
+(non-nightly) PyPI name stays untouched.
+
+This script (a) renames each bundle's ``[project] name`` to
+``<name>-nightly``, (b) bumps its version to ``<base>.dev<N>``, (c) rewrites
+its ``lfx`` runtime dep so it resolves against the renamed ``lfx-nightly``
+workspace member, and (d) updates the root ``pyproject.toml`` so its bundle
+deps and ``[tool.uv.sources]`` entries reference the renamed packages.
+
+All operations are idempotent — running twice is a no-op.
